AI Technical Summary

Benefits of technology

[0005]It has surprisingly now been found that a good anti-grey effect in water-based liquid detergents can be achieved without an unacceptable increase in viscosity or precipitation by using certain polycarbonate-, polyurethane- and / or polyurea-polyorganosiloxane compounds or precursor compounds of the reactive cyclic carbonate and urea type that may be used in the synthesis of such polycarbonate-, polyurethane- and / or polyurea-polyorganosiloxane compounds.

Problems solved by technology

Although the cellulose ethers mentioned above have a good anti-grey effect, there are such narrow limits to their use in water-based liquid detergents that in practice they cannot be incorporated into these detergents.
